Abstract:
Objective To study the synergistic antitumor effect of PCF when combine used with CTX.Methods Inoculated 0.2 mL H22 tumor fluid into the right armpit of mouse,and then the animals were divided into seven groups randomly: control group;CTX group(CTX 10 mg?kg-1);three test group(PCF 1000,500 and 250 mg?kg-1) and two combined use groups (PCF 1000,500 mg?kg-1with CTX 10 mg?kg-1).PCF were given by intragastric administration for 10 days,and CTX by intraperitoneal injection for 10 days.Same volume of saline was given to the control group.The mice were killed 24 hours after the last medication and the tumor inhibition rate was calculated.Results Three PCF groups had no effect on tumor inhibition,while two combined treatusement groups showed significant effect on tumor inhibition,while at the same doses the tumor inhibition rates were raised to 55.9% and 52.9% respectively,which were higher than that of CTX when used alone.Conclusion PCF can enhance the antitumor effects of CTX.
